Show more stack trace of CompositeException

See original GitHub issue

This is an example stack trace of a CompositeException:

com.linecorp.armeria.common.util.CompositeException: 2 exceptions occurred. 
	at com.linecorp.armeria.common.stream.AbstractStreamMessage$CloseEvent.notifySubscriber(AbstractStreamMessage.java:273)
	at com.linecorp.armeria.common.stream.DefaultStreamMessage.notifySubscriberOfCloseEvent0(DefaultStreamMessage.java:300)
	at com.linecorp.armeria.common.stream.DefaultStreamMessage.lambda$notifySubscriberOfCloseEvent$3(DefaultStreamMessage.java:294)

	at java.base/java.lang.Thread.run(Thread.java:835)
Caused by: com.linecorp.armeria.common.util.CompositeException$ExceptionOverview: Multiple exceptions (2)
|-- java.util.NoSuchElementException: null
    at java.base/java.util.ArrayDeque.getLast(ArrayDeque.java:413)
|-- com.linecorp.armeria.common.stream.AbortedStreamException: null
    at com.linecorp.armeria.common.stream.AbortedStreamException.get(AbortedStreamException.java:39)

The exceptions in ExceptionOverview just show two lines of stack traces so it’s really hard to get a context what’s going on from it. We might need to increase the lines (20 is sensible default?) and show full stack trace when -Dcom.linecorp.armeria.verboseExceptions=true.

allowing the user to set the number of lines that are output?

That’s a good suggestion. 👍 However, I’m a bit reluctant to do that because

CompositeException is not something that users create by themselves
We need another system property flag to indicate the number of lines which adds another public API that might not be needed.

Therefore, how about just using the verboseExceptions property for now? If there’re demands for the number of lines later, we can add it at that time. 😄
